随机的

介绍

Random provides access to Python’s urandom module, which is available by default in VEXcode IQ (2nd gen). These methods let you generate random numbers, floats, and values from lists or ranges—useful for adding unpredictability to games, behaviors, and autonomous decision-making.

以下是可用方法的列表：

• randint – Returns a random integer between two values (inclusive).

• uniform – Returns a random float between two values.

• randrange – Returns a random integer from a range with an optional step.

数字生成器

randint

randint returns a random integer between two values (inclusive), where both values are integers.

Usage:
urandom.randint(a, b)

范围	描述
a	表示范围的包含下限的整数。
b	表示范围上限的整数。

# Generate a random integer between
# 1 and 10 (inclusive)
urandom_int = urandom.randint(1, 10)
brain.screen.print(urandom_int)

# urandom_int = (random integer between 1 and 10)

uniform

uniform returns a random float between two values, where both values are floats or integers.

Usage:
urandom.uniform(start, end)

范围	描述
start	表示范围下限的浮点数或整数。
end	表示范围上限的浮点数或整数。

# Generate a random float 
# between 5.0 and 10.0
urandom_uniform = urandom.uniform(5.0, 10.0)
brain.screen.print(urandom_uniform)

# urandom_uniform = (random float 
# between 5.0 and 10.0)

randrange

randrange returns a random integer from a range with an optional step, where both the start and stop values are integers.

Usage:
urandom.randrange(start, stop, step)

范围	描述
start	可选。一个整数，表示范围的起始值（含）。默认值为 0。
stop	表示范围的唯一结束值的整数。
step	可选。一个整数，表示范围内每个数字之间的差值。默认值为 1。

# Generate a random integer from
# 0 to 9 (exclusive of 10)
urandom_range = urandom.randrange(10)
brain.screen.print(urandom_range)

# urandom_range = (random integer from 0 to 9)

# Generate a random integer from
# 5 to 15 (exclusive of 15)
urandom_range = urandom.randrange(5, 15)
brain.screen.print(urandom_range)

# urandom_range = (random integer from 5 to 14)

# Generate a random integer from
# 10 to 50, stepping by 5
urandom_range = urandom.randrange(10, 50, 5)
brain.screen.print(urandom_range)

# urandom_range = (random multiple of 5 between 10 and 45)
